MCO-5211
Master Sync Change-Over
Cost-efficient performance and versatility.
The MCO-5211 master sync change-over from
Grass Valley, a Belden Brand, is designed for use
in both serial digital and analog television environment, including AES3 digital audio signals. The use
of a change-over unit greatly improves the reliability
of a single SPG by having a backup unit ready for
takeover in the event of an SPG break down. In order
to improve the reliability of the complete system it
is essential to have a simple change-over unit. This
ensures that the system reliability will not be compromised by the complexity of the change-over unit
which then becomes the single point of failure.
The MSG-5300 has independent circuit for monitoring the signal quality on their outputs. A choice of
outputs to be monitored is possible. Errors (too low
levels or no transitions) will trigger an alarm signal.
This signal is used in the MCO-5211 change-over
unit to switch to the backup SPG. Since the changeover unit relies on alarm signals from the SPGs, the
complexity of the unit itself is reduced and the total
system reliability is improved.
The MCO-5211 master sync change-over unit automatically switches SDI, composite video, composite blackburst, AES3 digital audio and LTC signals
between the primary and the backup generator.

The change-over unit can be configured to fit the
exact configuration of the SPGs used in connection
with the change-over unit. The switching is done by
means of relays with all channels switched simultaneously. The use of latching relays ensures that the
SPG selection remains unchanged in case of power
failure on the change-over unit.
Front panel control is provided to select which generator is to be the primary one (operating mode manual or automatic). The front panel is secured against
accidental changes by including a “Hold to Modify”
button which must be pressed simultaneously with
any other button.
Remote control is facilitated by a parallel remote
interface. For emergency situations the remote can
always be overruled by the front panel controls. A
simple relay contact in the remote connector may
be used to connect an external warning circuit. The
contact is open during normal operation and closes
during failure. This relay may be used to activate an
external alarm in the event of a failure — even in case
of missing power to the change-over system.
